Vienna's statements and actions surrounding the case of an ex-army colonel accused of spying for Moscow are based on suspicions, and there is no evidence backing them up, the Russian Foreign Ministry said in a press statement Friday.
"We emphasized that the steps taken by Vienna, based on suspicions without any evidence whatsoever, have already led to the complication of our relations, which until recently enjoyed a positive dynamic," the Foreign Ministry added.
Ambassador Aigner was summoned to the Russian Foreign Ministry Friday afternoon over the diplomatic incident.
The Foreign Ministry handed Ambassador Aigner an official note of protest, and informed him that Moscow is "puzzled" by the fact that its Austrian partners "chose not to discuss their suspicions with us through the established channels of dialogue, but instead resorted to what has unfortunately become the customary method for many Western countries — the sensational injection of false information in the media and a public demand for an explanation from Russia. This approach is not acceptable," the statement stressed.
Ambassador Aigner promised to "immediately inform" Vienna about the Russian protest, the statement concluded.
Later in the day, Austrian Prime Minister Sebastian Kurz confirmed that Vienna had detained an ex-officer suspected of spying for Russia, and said he would discuss further steps with his fellow EU member partners if the suspicions proved to be true. Kurz urged Russia to provide "transparent" information on the situation. Austrian Foreign Minister Karin Kneissl summoned a Russian official and cancelled a scheduled trip to Russia over the incident.
Commenting on the case, Russian Foreign Minister Sergei Larvov said the allegations "unpleasantly surprised" him, and said he lamented that Austria seems to have resorted to what he called "megaphone diplomacy."
